. IMPROVEMENT IN HUB-'BORlNG MACHLNES.

Specification forming part of Letters Patent No. 198,081 dated December11, 1877; application filed April 16, 1877. 7

To all whom it may concern:

Be it known that I, JAMES C. OoRNEIL, of

Lowder, in the county of Sangamon and State of Illinois, have invented anew and Improved Hub-Boring Machine, of which the following is aspecification I In the accompanying drawing, Figure 1 represents a sideelevation of my improved hub-boxing machine; Fig. 2 a horizontal sectionof the I same on line as m, Fig. 1; Fig. 3, a detail view of theshafting for driving the machine by power; and Figs. 4 and 5 are,respectively, an end View and a cross-section on line y 3 Fig. 3, of thepowenshaft attachment.

Similar letters of reference indicate corresponding parts.

This invention has reference to an improved hand or power machine forcutting or borin g out the hubs of all kinds of wheels for the insertionof the boxes in a rapid and economical manner; and the inventionconsists of a bench, with sliding carriages supporting the hub oririction-rollers, and retaining the same by top I band and rear brace.

An adjustable cutting-knife is carriedalong the inside of the revolvinghub by a feed-screw and hook -shaft, operated by a detachable hand-crankor power attachment. I

In the drawing, A represents the supporting-bench of my improvedboxing-machine, which is laterally adjusted tothe size of the hub byslides and wedge-pieces. On the bench are arranged the adjustablecarriages B, which are guided in fixed rails a and adjusted toward fixedposts B by screwbolts 1) with operating hand-cranks.

The hub of the wheel is placed on frictionrollers d of the carriages B,which rollers turn in recesses d of the carriages, and are placed eitherin the inner or outer set of recesses or notches, according as the hubis supported with its smaller or larger end thereon. The

changing of the friction-rollers in the carriages admits the support ofthe hub in horizontal position, whether the thinner end of the hub isseated in one or the opposite direction on the carriages.

When the hub is placed in position on the carriages, the top band D,which is also provided with friction-rollers, is placed on the top ofthe hub, and screwed tightly by thumb-screws c turning on the pivotedscrew-rods e of the front carriage, which enter recesses of band D. The

hub is thus retained firmly in position on the v to studs f of theknife-shaft F, which is secured at the outer end to a lateralcross-bolt, g, of a sliding frame, F, and adjusted by top and bottomcrank-screws in the same so as V to be set to the exact height required.

The frame F. is guided on an extension, A, of bench A, against a lateralbrace, h, of which the hub rests when in position on the carriages.

A pronged grab, G, is next driven into the end-of the hub after beingpassed by its center hole over the feed-screw E, to which the adjustablehand-crank H is then applied by being closed around the feed-screw shaftby its pivot-lever H, which operates a movable tap of the crank againsta fixed tap of the same. The taps of the crank H are provided with hookst, which engage the grab G, so that by turning the lever the taps engagethe feedscrew, and the hooks the grab, producing the motion of thefeed-screw shaft simultaneously with the turning of the hub.

The knife-shaft is. provided with a suitable detachableandinterchangeable cuttin g-knife, which is carried against the innerside of the hub, and drawn through the same by the action of thefeed-shaft and crank so as to bore out the hub to the required degreefor theinsertion of the box.

The proper taper of the hole is obtained by adjusting the carriages B ofthe bench by means .of their cranks in such a manner that the axis ofthe hub forms a small angle of inclination with the transverse axis ofthe bench. In this manner, any required degree of taper may be obtainedfor the bore-hole in quick manner. The knife-shaft is adjusted to thehub by thesetscrews of slide-frame F in vertical or horizontal.direction until the proper position for cutting is obtained, and alsothe hub to the knife by the sliding carriages. The hub may be bored fromthe larger or smaller end, it being readily reversed on the carriages bychanging the position of the friction-rollers into the outer or innernotches or recesses.

When the hub is bored about half-way the crank is taken off by turningthe lever slightly in opposite direction, to produce the opening of thetaps and admit the easy clearing of the feed-screw. The slide-frameisthen pulled back, and if the hole is not large enough the knife andhub are reset until the desired size and taper are obtained.

The friction-rollers facilitate the easy turning of the hub against thecutting-knife by means of the detachable crank. The crank may be made indifferent ways, provided it closes tightly by its tap sections on thefeedshaft, when turning the hub in one direction, but releases thefeed-shaft when turned in opposite direction.

The machine may also be used with steam or otherpower, for which theattachment shown in Figs. 3, 4, and 5 -is used. The hook ends engage thegrab in the same manner as before, while the feed-rod runs into a hollowor socket part when boring. The socket part connects with a shaft andclutch mechanism to admit the throwing in and out of gear with thedriving-shaft, and enabling the operator to interrupt the cutting of theknife without stopping the motion of the driving-shaft.

The hubs may be thus bored out in easy, quick, and accurate manner, andthereby considerable time and labor saved in boxing wheels.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A hub-boxing machine, consisting of a JAMESGORNEILUS (JORNEIL.
